Sure the criminals share responsible. But guess what, they're criminals. The fact that criminals act with no sense of responsibility or accountability toward the rest of us is why we have the police in the first place. Their function is to step in and provide what the criminals are taking away from the community. Instead, they're doubling down on the effect the criminals have and are making things worse.
I'm not asking anyone to ignore anything. But that doesn't mean that what arises from their actions ceases to be their responsibility.
